Storm Front: NA Fantasy/Time Travel (Tesla Time Travelers #3)

Family. Lies. Lightning.
 
There are some things Evy can count on. Her lightning has never failed her. But she never asked why. She never asked where it came from or why it's been so faithful.
Before now... She never asked who was she without it.

~~~ Tesla's Time Travlelers. Book 3 ~~~
With the people she can trust dwindling to a handful, Evy must again head into danger. This time, she’ll have Constantine at her side, and she’ll need him.
But guiding a Roman warrior through his future brings a host of complications she didn’t plan for and with her sister missing, Evy can’t risk more unknowns. At least, not without another trip back to see her friend Nikola Tesla to uncover the real story of the Lightning Riders and the history of her mentors.
With Penya on the loose and Ilif’s lies too tangled with the truth, Evy must balance the knife’s edge of asking for help and believing people who want her power.
The same ones willing to kill to get what they want.
